BACKGROUND OF THE INVENTION

Epigenetic regulation of gene expression is an important biologicaldeterminant of protein production and cellular differentiation and playsa significant pathogenic role in a number of human diseases.

Epigenetic regulation involves heritable modification of geneticmaterial without changing its nucleotide sequence. Typically, epigeneticregulation is mediated by selective and reversible modification (e.g.,methylation) of DNA and proteins (e.g., histones) that control theconformational transition between transcriptionally active and inactivestates of chromatin. These covalent modifications can be controlled byenzymes such as methyltransferases (e.g., arginine methyltransferases),many of which are associated with specific genetic alterations that cancause human disease.

Disease-associated chromatin-modifying enzymes (e.g., argininemethyltransferases) play a role in diseases such as proliferativedisorders, autoimmune disorders, muscular disorders, vascular disorders,metabolic disorders, and neurological disorders. Thus, there is a needfor the development of small molecules that are capable of inhibitingthe activity of arginine methyltransferases.

“Partially unsaturated” refers to a group that includes at least onedouble or triple bond. The term “partially unsaturated” is intended toencompass rings having multiple sites of unsaturation, but is notintended to include aromatic groups (e.g., aryl or heteroaryl groups) asherein defined. Likewise, “saturated” refers to a group that does notcontain a double or triple bond, i.e., contains all single bonds.

In some embodiments, alkyl, alkenyl, alkynyl, carbocyclyl, heterocyclyl,aryl, and heteroaryl groups, as defined herein, are optionallysubstituted (e.g., “substituted” or “unsubstituted” alkyl, “substituted”or “unsubstituted” alkenyl, “substituted” or “unsubstituted” alkynyl,“substituted” or “unsubstituted” carbocyclyl, “substituted” or“unsubstituted” heterocyclyl, “substituted” or “unsubstituted” aryl or“substituted” or “unsubstituted” heteroaryl group). In general, the term“substituted”, whether preceded by the term “optionally” or not, meansthat at least one hydrogen present on a group (e.g., a carbon ornitrogen atom) is replaced with a permissible substituent, e.g., asubstituent which upon substitution results in a stable compound, e.g.,a compound which does not spontaneously undergo transformation such asby rearrangement, cyclization, elimination, or other reaction. Unlessotherwise indicated, a “substituted” group has a substituent at one ormore substitutable positions of the group, and when more than oneposition in any given structure is substituted, the substituent iseither the same or different at each position. The term “substituted” iscontemplated to include substitution with all permissible substituentsof organic compounds, including any of the substituents described hereinthat results in the formation of a stable compound. The presentdisclosure contemplates any and all such combinations in order to arriveat a stable compound. For purposes of this disclosure, heteroatoms suchas nitrogen may have hydrogen substituents and/or any suitablesubstituent as described herein which satisfy the valencies of theheteroatoms and results in the formation of a stable moiety.

“Pharmaceutically acceptable salt” refers to those salts which are,within the scope of sound medical judgment, suitable for use in contactwith the tissues of humans and other animals without undue toxicity,irritation, allergic response, and the like, and are commensurate with areasonable benefit/risk ratio. Pharmaceutically acceptable salts arewell known in the art. For example, Berge et al. describepharmaceutically acceptable salts in detail in J. PharmaceuticalSciences (1977) 66:1-19. Pharmaceutically acceptable salts of thecompounds describe herein include those derived from suitable inorganicand organic acids and bases. Examples of pharmaceutically acceptable,nontoxic acid addition salts are salts of an amino group formed withinorganic acids such as hydrochloric acid, hydrobromic acid, phosphoricacid, sulfuric acid and perchloric acid or with organic acids such asacetic acid, oxalic acid, maleic acid, tartaric acid, citric acid,succinic acid, or malonic acid or by using other methods used in the artsuch as ion exchange. Other pharmaceutically acceptable salts includeadipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate,bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate,cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate,formate, fumarate, glucoheptonate, glycerophosphate, gluconate,hemisulfate, heptanoate, hexanoate, hydroiodide,2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, laurylsulfate, malate, maleate, malonate, methanesulfonate,2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate,pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate,pivalate, propionate, stearate, succinate, sulfate, tartrate,thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and thelike. Salts derived from appropriate bases include alkali metal,alkaline earth metal, ammonium and N⁺(C₁₋₄alkyl)₄ salts. Representativealkali or alkaline earth metal salts include sodium, lithium, potassium,calcium, magnesium, and the like. Further pharmaceutically acceptablesalts include, when appropriate, quaternary salts.

A “subject” to which administration is contemplated includes, but is notlimited to, humans (e.g., a male or female of any age group, e.g., apediatric subject (e.g, infant, child, adolescent) or adult subject(e.g., young adult, middle-aged adult or senior adult)) and/or othernon-human animals, for example, non-human mammals (e.g., primates (e.g.,cynomolgus monkeys, rhesus monkeys); commercially relevant mammals suchas cattle, pigs, horses, sheep, goats, cats, and/or dogs), birds (e.g.,commercially relevant birds such as chickens, ducks, geese, and/orturkeys), rodents (e.g., rats and/or mice), reptiles, amphibians, andfish. In certain embodiments, the non-human animal is a mammal. Thenon-human animal may be a male or female at any stage of development. Anon-human animal may be a transgenic animal.

“Condition,” “disease,” and “disorder” are used interchangeably herein.

“Treat,” “treating” and “treatment” encompasses an action that occurswhile a subject is suffering from a condition which reduces the severityof the condition or retards or slows the progression of the condition(“therapeutic treatment”). “Treat,” “treating” and “treatment” alsoencompasses an action that occurs before a subject begins to suffer fromthe condition and which inhibits or reduces the severity of thecondition (“prophylactic treatment”).

An “effective amount” of a compound refers to an amount sufficient toelicit the desired biological response, e.g., treat the condition. Aswill be appreciated by those of ordinary skill in this art, theeffective amount of a compound described herein may vary depending onsuch factors as the desired biological endpoint, the pharmacokinetics ofthe compound, the condition being treated, the mode of administration,and the age and health of the subject. An effective amount encompassestherapeutic and prophylactic treatment.

A “therapeutically effective amount” of a compound is an amountsufficient to provide a therapeutic benefit in the treatment of acondition or to delay or minimize one or more symptoms associated withthe condition. A therapeutically effective amount of a compound means anamount of therapeutic agent, alone or in combination with othertherapies, which provides a therapeutic benefit in the treatment of thecondition. The term “therapeutically effective amount” can encompass anamount that improves overall therapy, reduces or avoids symptoms orcauses of the condition, or enhances the therapeutic efficacy of anothertherapeutic agent.

A “prophylactically effective amount” of a compound is an amountsufficient to prevent a condition, or one or more symptoms associatedwith the condition or prevent its recurrence. A prophylacticallyeffective amount of a compound means an amount of a therapeutic agent,alone or in combination with other agents, which provides a prophylacticbenefit in the prevention of the condition. The term “prophylacticallyeffective amount” can encompass an amount that improves overallprophylaxis or enhances the prophylactic efficacy of anotherprophylactic agent.

As used herein, the term “methyltransferase” represents transferaseclass enzymes that are able to transfer a methyl group from a donormolecule to an acceptor molecule, e.g., an amino acid residue of aprotein or a nucleic base of a DNA molecule. Methytransferases typicallyuse a reactive methyl group bound to sulfur in S-adenosyl methionine(SAM) as the methyl donor. In some embodiments, a methyltransferasedescribed herein is a protein methyltransferase. In some embodiments, amethyltransferase described herein is a histone methyltransferase.Histone methyltransferases (HMT) are histone-modifying enzymes,(including histone-lysine N-methyltransferase and histone-arginineN-methyltransferase), that catalyze the transfer of one or more methylgroups to lysine and arginine residues of histone proteins. In certainembodiments, a methyltransferase described herein is a histone-arginineN-methyltransferase.

Injectable preparations, for example, sterile injectable aqueous oroleaginous suspensions can be formulated according to the known artusing suitable dispersing or wetting agents and suspending agents. Thesterile injectable preparation can be a sterile injectable solution,suspension or emulsion in a nontoxic parenterally acceptable diluent orsolvent, for example, as a solution in 1,3-butanediol. Among theacceptable vehicles and solvents that can be employed are water,Ringer's solution, U.S.P. and isotonic sodium chloride solution. Inaddition, sterile, fixed oils are conventionally employed as a solventor suspending medium. For this purpose any bland fixed oil can beemployed including synthetic mono- or diglycerides. In addition, fattyacids such as oleic acid are used in the preparation of injectables.

The injectable formulations can be sterilized, for example, byfiltration through a bacterial-retaining filter, or by incorporatingsterilizing agents in the form of sterile solid compositions which canbe dissolved or dispersed in sterile water or other sterile injectablemedium prior to use.

In order to prolong the effect of a drug, it is often desirable to slowthe absorption of the drug from subcutaneous or intramuscular injection.This can be accomplished by the use of a liquid suspension ofcrystalline or amorphous material with poor water solubility. The rateof absorption of the drug then depends upon its rate of dissolutionwhich, in turn, may depend upon crystal size and crystalline form.Alternatively, delayed absorption of a parenterally administered drugform is accomplished by dissolving or suspending the drug in an oilvehicle.

Compositions for rectal or vaginal administration are typicallysuppositories which can be prepared by mixing the compounds describedherein with suitable non-irritating excipients or carriers such as cocoabutter, polyethylene glycol or a suppository wax which are solid atambient temperature but liquid at body temperature and therefore melt inthe rectum or vaginal cavity and release the active ingredient.

Solid dosage forms for oral administration include capsules, tablets,pills, powders, and granules. In such solid dosage forms, the activeingredient is mixed with at least one inert, pharmaceutically acceptableexcipient or carrier such as sodium citrate or dicalcium phosphateand/or a) fillers or extenders such as starches, lactose, sucrose,glucose, mannitol, and silicic acid, b) binders such as, for example,carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone,sucrose, and acacia, c) humectants such as glycerol, d) disintegratingagents such as agar, calcium carbonate, potato or tapioca starch,alginic acid, certain silicates, and sodium carbonate, e) solutionretarding agents such as paraffin, f) absorption accelerators such asquaternary ammonium compounds, g) wetting agents such as, for example,cetyl alcohol and glycerol monostearate, h) absorbents such as kaolinand bentonite clay, and i) lubricants such as talc, calcium stearate,magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate,and mixtures thereof. In the case of capsules, tablets and pills, thedosage form may comprise buffering agents.

Solid compositions of a similar type can be employed as fillers in softand hard-filled gelatin capsules using such excipients as lactose ormilk sugar as well as high molecular weight polyethylene glycols and thelike. The solid dosage forms of tablets, dragees, capsules, pills, andgranules can be prepared with coatings and shells such as entericcoatings and other coatings well known in the pharmaceutical formulatingart. They may optionally comprise opacifying agents and can be of acomposition that they release the active ingredient(s) only, orpreferentially, in a certain part of the intestinal tract, optionally,in a delayed manner. Examples of embedding compositions which can beused include polymeric substances and waxes. Solid compositions of asimilar type can be employed as fillers in soft and hard-filled gelatincapsules using such excipients as lactose or milk sugar as well as highmolecular weight polyethylene glycols and the like.

The active ingredient can be in micro-encapsulated form with one or moreexcipients as noted above. The solid dosage forms of tablets, dragees,capsules, pills, and granules can be prepared with coatings and shellssuch as enteric coatings, release controlling coatings and othercoatings well known in the pharmaceutical formulating art. In such soliddosage forms the active ingredient can be admixed with at least oneinert diluent such as sucrose, lactose, or starch. Such dosage forms maycomprise, as is normal practice, additional substances other than inertdiluents, e.g., tableting lubricants and other tableting aids such amagnesium stearate and microcrystalline cellulose. In the case ofcapsules, tablets, and pills, the dosage forms may comprise bufferingagents. They may optionally comprise opacifying agents and can be of acomposition that they release the active ingredient(s) only, orpreferentially, in a certain part of the intestinal tract, optionally,in a delayed manner. Examples of embedding compositions which can beused include polymeric substances and waxes.

Dosage forms for topical and/or transdermal administration of a providedcompound may include ointments, pastes, creams, lotions, gels, powders,solutions, sprays, inhalants and/or patches. Generally, the activeingredient is admixed under sterile conditions with a pharmaceuticallyacceptable carrier and/or any desired preservatives and/or buffers ascan be required. Additionally, the present disclosure encompasses theuse of transdermal patches, which often have the added advantage ofproviding controlled delivery of an active ingredient to the body.

Compounds and compositions described herein are generally useful for theinhibition of RMT (e.g., PRMT1, PRMT3, CARM1, PRMT6, and/or PRMT8). Insome embodiments, methods of treating an RMT-mediated disorder in asubject are provided which comprise administering an effective amount ofa compound described herein (e.g., a compound of Formula (I)), or apharmaceutically acceptable salt thereof), to a subject in need oftreatment.

In certain embodiments,the subject is suffering from a RMT-mediated disorder. In certainembodiments, the subject is susceptible to a RMT-mediated disorder.

As used herein, the term “RMT-mediated disorder” means any disease,disorder, or other pathological condition in which an RMT (e.g., PRMT1,PRMT3, CARM1, PRMT6, and/or PRMT8) is known to play a role. Accordingly,in some embodiments, the present disclosure relates to treating orlessening the severity of one or more diseases in which an RMT is knownto play a role.

In some embodiments, the present disclosure provides a method ofinhibiting an RMT comprising contacting the RMT with an effective amountof a compound described herein (e.g., a compound of Formula (I)), or apharmaceutically acceptable salt thereof. The RMT may be purified orcrude, and may be present in a cell, tissue, or subject. Thus, suchmethods encompass both inhibition of in vitro and in vivo RMT activity.In certain embodiments, the method is an in vitro method, e.g., such asan assay method. It will be understood by one of ordinary skill in theart that inhibition of an RMT does not necessarily require that all ofthe RMT be occupied by an inhibitor at once. Exemplary levels ofinhibition of an RMT (e.g., PRMT1, PRMT3, CARM1, PRMT6, and/or PRMT8)include at least 10% inhibition, about 10% to about 25% inhibition,about 25% to about 50% inhibition, about 50% to about 75% inhibition, atleast 50% inhibition, at least 75% inhibition, about 80% inhibition,about 90% inhibition, and greater than 90% inhibition.

In certain embodiments, thesubject is a cancer patient.

In some embodiments, a compound provided herein is useful in treating aproliferative disorder, such as cancer. For example, while not beingbound to any particular mechanism, protein arginine methylation by PRMTsis a modification that has been implicated in signal transduction, genetranscription, DNA repair and mRNA splicing, among others; andoverexpression of PRMTs within these pathways is often associated withvarious cancers. Thus, compounds which inhibit the action of PRMTs, asprovided herein, are effective in the treatment of cancer.

In some embodiments, compounds provided herein are effective in treatingcancer through the inhibition of PRMT1. For example, PRMT1overexpression has been observed in various human cancers, including,but not limited to, breast cancer, prostate cancer, lung cancer, coloncancer, bladder cancer, and leukemia. In one example, PRMT1 specificallydeposits an asymmetric dimethylarginine (aDMA) mark on histone H4 atarginine 3 (H4R3me2a), and this mark is associated with transcriptionactivation. In prostate cancer, the methylation status of H4R3positively correlates with increasing tumor grade and can be used topredict the risk of prostate cancer recurrence (Seligson et al., Nature2005 435, 1262-1266). Thus, in some embodiments, inhibitors of PRMT1, asdescribed herein, are useful in treating cancers associated with themethylation status of H4R3, e.g., prostate cancer. Additionally, themethylarginine effector molecule TDRD3 interacts with the H4R3me2a mark,and overexpression of TDRD3 is linked to poor prognosis for the survivalof patients with breast cancer (Nagahata et al., Cancer Sci. 2004 95,218-225). Thus, in some embodiments, inhibitors of PRMT1, as describedherein, are useful in treating cancers associated with overexpression ofTDRD3, e.g., breast cancer, as inhibition of PRMT1 leads to a decreasein methylation of H4R3, thereby preventing the association ofoverexpressed TDRD3 with H4R3me2a. In other examples, PRMT1 is known tohave non-histone substrates. For example, PRMT1, when localized to thecytoplasm, methylates proteins that are involved in signal transductionpathways, e.g., the estrogen receptor (ER). The expression status of ERin breast cancer is critical for prognosis of the disease, and bothgenomic and non-genomic ER pathways have been implicated in thepathogenesis of breast cancer. For example, it has been shown that PRMT1methylates ERα, and that ERα methylation is required for the assembly ofERα with SRC (a proto-oncogene tyrosine-protein kinase) and focaladhesion kinase (FAK). Further, the silencing of endogenous PRMT1resulted in the inability of estrogen to activate AKT. These resultssuggested that PRMT1-mediated ERα methylation is required for theactivation of the SRC-PI3K-FAK cascade and AKT, coordinating cellproliferation and survival. Thus, hypermethylation of ERα in breastcancer is thought to cause hyperactivation of this signaling pathway,providing a selective survival advantage to tumor cells (Le Romancer etal., Mol. Cell 2008 31, 212-221; Le Romancer et al., Steroids 2010 75,560-564). Accordingly, in some embodiments, inhibitors of PRMT1, asdescribed herein, are useful in treating cancers associated with ERαmethylation, e.g., breast cancer. In yet another example, PRMT1 has beenshown to be involved in the regulation of leukemia development. Forexample, SRC-associated in mitosis 68 kDa protein (SAM68; also known asKHDRBS1) is a well-characterized PRMT1 substrate, and when either SAM68or PRMT1 is fused directly to the myeloid/lymphoid leukemia (MLL) gene,these fusion proteins can activate MLL oncogenic properties, implyingthat the methylation of SAM68 by PRMT1 is a critical signal for thedevelopment of leukemia (Cheung et al., Nature Cell Biol. 2007 9,1208-1215). Accordingly, in some embodiments, inhibitors of PRMT1, asdescribed herein, are useful in treating cancers associated with SAM68methylation, e.g., leukemia. In still another example, PRMT1 isimplicated in leukemia development through its interaction with AE9a, asplice isoform of AML1-ETO (Shia et al., Blood 2012 119:4953-62).Knockdown of PRMT1 affects expression of certain AE9a-activated genesand suppresses AE9a's self-renewal capability. It has also been shownthat AE9a recruits PRMT1 to AE9a activated gene promoters, which leadsto increased H4 Arg3 methylation, H3 Lys9/14 acetylation, andtranscription activated. Accordingly, in some embodiments, inhibitors ofPRMT1, as described herein, are useful in treating cancers associatedwith AML1-ETO, e.g., leukemia. Thus, without being bound by anyparticular mechanism, the inhibition of PRMT1, e.g., by compoundsdescribed herein, is beneficial in the treatment of cancer.

In some embodiments, compounds provided herein are effective in treatingcancer through the inhibition of PRMT3. In one example, the DAL tumorsuppressor protein has been shown to interact with PRMT3 and inhibitsits methyltransferase activity (Singh et al., Oncogene 2004 23,7761-7771). Epigenetic downregulation of DAL has been reported inseveral cancers (e.g., meningiomas and breast cancer), thus PRMT3 isexpected to display increased activity, and cancers that display DALsilencing may, in some aspects, be good targets for PRMT3 inhibitors,e.g., those described herein. Thus, without being bound by anyparticular mechanism, the inhibition of PRMT3, e.g., by compoundsdescribed herein, is beneficial in the treatment of cancer.

In some embodiments, compounds provided herein are effective in treatingcancer through the inhibition of PRMT4, also known as CARM1. Forexample, PRMT4 levels have been shown to be elevated incastration-resistant prostate cancer (CRPC), as well as in aggressivebreast tumors (Hong et al., Cancer 2004 101, 83-89; Majumder et al.,Prostate 2006 66, 1292-1301). Thus, in some embodiments, inhibitors ofPRMT4, as described herein, are useful in treating cancers associatedwith PRMT4 overexpression. PRMT4 has also been shown to affectERα-dependent breast cancer cell differentiation and proliferation(Al-Dhaheri et al., Cancer Res. 201171, 2118-2128), thus in some aspectsPRMT4 inhibitors, as described herein, are useful in treatingERα-dependent breast cancer by inhibiting cell differentiation andproliferation. In another example, PRMT4 has been shown to be recruitedto the promoter of E2F1 (which encodes a cell cycle regulator) as atranscriptional co-activator (Frietze et al., Cancer Res. 2008 68,301-306). Thus, PRMT4-mediated upregulation of E2F1 expression maycontribute to cancer progression and chemoresistance as increasedabundance of E2F1 triggers invasion and metastasis by activating growthreceptor signaling pathways, which in turn promote an antiapoptotictumor environment (Engelmann and Putzer, Cancer Res 2012 72; 571).Accordingly, in some embodiments, the inhibition of PRMT4, e.g., bycompounds provided herein, is useful in treating cancers associated withE2F1 upregulation. Thus, without being bound by any particularmechanism, the inhibition of PRMT4, e.g., by compounds described herein,is beneficial in the treatment of cancer.

In some embodiments, compounds provided herein are effective in treatingcancer through the inhibition of PRMT6. For example, PRMT6 has beenreported to be overexpressed in a number of cancers, e.g., bladder andlung cancer (Yoshimatsu et al., Int. J. Cancer 2011 128, 562-573). Thus,in some embodiments, the inhibition of PRMT6, by compounds providedherein, is useful in treating cancers associated with PRMT6overexpression. In some aspects, PRMT6 is primarily thought to functionas a transcriptional repressor, although it has also been reported thatPRMT6 functions as a co-activator of nuclear receptors. For example, asa transcriptional repressor, PRMT6 suppresses the expression ofthrombospondin 1 (TSP1; also known as THBS1; a potent natural inhibitorof angiogenesis and endothelial cell migration) and p21 (a naturalinhibitor of cyclin dependent kinase), thereby contributing to cancerdevelopment and progression (Michaud-Levesque and Richard, J. Biol.Chem. 2009 284, 21338-21346; Kleinschmidt et al., PLoS ONE 2012 7,e41446). Accordingly, in some embodiments, the inhibition of PRMT6, bycompounds provided herein, is useful in treating cancer by preventingthe repression of THBs1 and/or p21. Thus, without being bound by anyparticular mechanism, the inhibition of PRMT6, e.g., by compoundsdescribed herein, is beneficial in the treatment of cancer.

In some embodiments, compounds provided herein are effective in treatingcancer through the inhibition of PRMT8. For example, deep-sequencingefforts of cancer genomes (e.g., COSMIC) have revealed that of all thePRMTs, PRMT8 is reported to be the most mutated. Of 106 sequencedgenomes, 15 carry mutations in the PRMT8 coding region, and nine ofthese result in an amino acid change (Forbes et al., Nucleic Acids Res.201139, D945-D950). Because of its high rate of mutation in cancer,PRMT8 is thought to contribute to the initiation or progression ofcancer. Thus, without being bound by any particular mechanism, theinhibition of PRMT8, e.g., by compounds described herein, is beneficialin the treatment of cancer.

In some embodiments, compounds described herein are useful for treatinga cancer including, but not limited to, acoustic neuroma,adenocarcinoma, adrenal gland cancer, anal cancer, angiosarcoma (e.g.,lymphangiosarcoma, lymphangioendotheliosarcoma, hemangiosarcoma),appendix cancer, benign monoclonal gammopathy, biliary cancer (e.g.,cholangiocarcinoma), bladder cancer, breast cancer (e.g., adenocarcinomaof the breast, papillary carcinoma of the breast, mammary cancer,medullary carcinoma of the breast), brain cancer (e.g., meningioma;glioma, e.g., astrocytoma, oligodendroglioma; medulloblastoma), bronchuscancer, carcinoid tumor, cervical cancer (e.g., cervicaladenocarcinoma), choriocarcinoma, chordoma, craniopharyngioma,colorectal cancer (e.g., colon cancer, rectal cancer, colorectaladenocarcinoma), epithelial carcinoma, ependymoma, endotheliosarcoma(e.g., Kaposi's sarcoma, multiple idiopathic hemorrhagic sarcoma),endometrial cancer (e.g., uterine cancer, uterine sarcoma), esophagealcancer (e.g., adenocarcinoma of the esophagus, Barrett's adenocarinoma),Ewing sarcoma, eye cancer (e.g., intraocular melanoma, retinoblastoma),familiar hypereosinophilia, gall bladder cancer, gastric cancer (e.g.,stomach adenocarcinoma), gastrointestinal stromal tumor (GIST), head andneck cancer (e.g., head and neck squamous cell carcinoma, oral cancer(e.g., oral squamous cell carcinoma (OSCC), throat cancer (e.g.,laryngeal cancer, pharyngeal cancer, nasopharyngeal cancer,oropharyngeal cancer)), hematopoietic cancers (e.g., leukemia such asacute lymphocytic leukemia (ALL) (e.g., B-cell ALL, T-cell ALL), acutemyelocytic leukemia (AML) (e.g., B-cell AML, T-cell AML), chronicmyelocytic leukemia (CML) (e.g., B-cell CML, T-cell CML), and chroniclymphocytic leukemia (CLL) (e.g., B-cell CLL, T-cell CLL); lymphoma suchas Hodgkin lymphoma (HL) (e.g., B-cell HL, T-cell HL) and non-Hodgkinlymphoma (NHL) (e.g., B-cell NHL such as diffuse large cell lymphoma(DLCL) (e.g., diffuse large B-cell lymphoma (DLBCL)), follicularlymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma(CLL/SLL), mantle cell lymphoma (MCL), marginal zone B-cell lymphomas(e.g., mucosa-associated lymphoid tissue (MALT) lymphomas, nodalmarginal zone B-cell lymphoma, splenic marginal zone B-cell lymphoma),primary mediastinal B-cell lymphoma, Burkitt lymphoma, lymphoplasmacyticlymphoma (e.g., “Waldenström's macroglobulinemia”), hairy cell leukemia(HCL), immunoblastic large cell lymphoma, precursor B-lymphoblasticlymphoma and primary central nervous system (CNS) lymphoma; and T-cellNHL such as precursor T-lymphoblastic lymphoma/leukemia, peripheralT-cell lymphoma (PTCL) (e.g., cutaneous T-cell lymphoma (CTCL) (e.g.,mycosis fungiodes, Sezary syndrome), angioimmunoblastic T-cell lymphoma,extranodal natural killer T-cell lymphoma, enteropathy type T-celllymphoma, subcutaneous panniculitis-like T-cell lymphoma, anaplasticlarge cell lymphoma); a mixture of one or more leukemia/lymphoma asdescribed above; and multiple myeloma (MM)), heavy chain disease (e.g.,alpha chain disease, gamma chain disease, mu chain disease),hemangioblastoma, inflammatory myofibroblastic tumors, immunocyticamyloidosis, kidney cancer (e.g., nephroblastoma a.k.a.

In some embodiments, a compound provided herein is useful in treatingdiseases associated with increased levels of circulating asymmetricdimethylarginine (aDMA), e.g., cardiovascular disease, diabetes, kidneyfailure, renal disease, pulmonary disease, etc. Circulating aDMA isproduced by the proteolysis of asymmetrically dimethylated proteins.PRMTs which mediate aDMA methylation include, e.g., PRMT1, PRMT3, PRMT4,PRMT6, and PRMT8. aDMA levels are directly involved in various diseasesas aDMA is an endogenous competitive inhibitor of nitric oxide synthase(NOS), thereby reducing the production of nitric oxide (NO) (Vallance etal., J. Cardiovasc. Pharmacol. 1992 20 (Suppl. 12):S60-2). NO functionsas a potent vasodilator in endothelial vessels, and as such inhibitingits production has major consequences on the cardiovascular system. Forexample, since PRMT1 is a major enzyme that generates aDMA, thedysregulation of its activity is likely to regulate cardiovasculardiseases (Boger et al., Ann. Med. 2006 38:126-36), and otherpathophysiological conditions such as diabetes mellitus (Sydow et al.,Vasc. Med. 2005 10 (Suppl. 1):S35-43), kidney failure (Vallance et al.,Lancet 1992 339:572-5), and chronic pulmonary diseases (Zakrzewicz etal., BMC Pulm. Med. 2009 9:5). Additionally, it has been demonstratedthat the expression of PRMT1 and PRMT3 are increased in coronary heartdisease (Chen et al., Basic Res. Cardiol. 2006 101:346-53). In anotherexample, aDMA elevation is seen in patients with renal failure, due toimpaired clearance of this metabolite from the circulation (Jacobi etal., Am. J. Nephrol. 2008 28:224-37). Thus, circulating aDMA levels isobserved in many pathophysiological situations. Accordingly, withoutbeing bound by any particular mechanism, the inhibition of PRMTs, e.g.,by compounds described herein, results in the decrease of circulatingaDMA, which is beneficial in the treatment of diseases associated withincreased levels of circulating aDMA, e.g., cardiovascular disease,diabetes, kidney failure, renal disease, pulmonary disease, etc. Incertain embodiments, a compound described herein is useful for treatingor preventing vascular diseases.

In some embodiments, a compound provided herein is useful in treatingmetabolic disorders. For example, PRMT1 has been shown to enhance mRNAlevels of FoxO1 target genes in gluconeogenesis, which results inincreased hepatic glucose production, and knockdown of PRMT promotesinhibition of FoxO1 activity and thus inhibition of hepaticgluconeogenesis (Choi et al., Hepatology 2012 56:1546-56). Additionally,genetic haploinsufficiency of Prmt1 has been shown to reduce bloodglucose levels in mouse models. Thus, without being bound by anyparticular mechanism, the inhibition of PRMT1, e.g., by compoundsdescribed herein, is beneficial in the treating of metabolic disorders,such as diabetes. In some embodiments, a provided compound is useful intreating type I diabetes. In some embodiments, a provided compound isuseful in treating type II diabetes.

In some embodiments, a compound provided herein is useful in treatingmuscular dystrophies. For example, PRMT1, as well as PRMT3 and PRMT6,methylate the nuclear poly(A)-binding protein (PABPN1) in a regionlocated near its C-terminus (Perreault et al., J. Biol. Chem. 2007282:7552-62). This domain is involved in the aggregation of the PABPN1protein, and abnormal aggregation of this protein is involved in thedisease oculopharyngeal muscular dystrophy (Davies et al., Int. J.Biochem. Cell. Biol. 2006 38:1457-62). Thus, without being bound by anyparticular mechanism, the inhibition of PRMTs, e.g., by compoundsdescribed herein, is beneficial in the treatment of musculardystrophies, e.g., oculopharyngeal muscular dystrophy, by decreasing theamount of methylation of PABPN1, thereby decreasing the amount of PABPN1aggregation.

CARM1 is also the most abundant PRMT expressed in skeletal muscle cells,and has been found to selectively control the pathways modulatingglycogen metabolism, and associated AMPK (AMP-activated protein kinase)and p38 MAPK (mitogen-activated protein kinase) expression. See, e.g.,Wang et al., Biochem (2012) 444:323-331. Thus, in some embodiments,inhibitors of CARM1, as described herein, are useful in treatingmetabolic disorders, e.g., for example skeletal muscle metabolicdisorders, e.g., glycogen and glucose metabolic disorders. Exemplaryskeletal muscle metabolic disorders include, but are not limited to,Acid Maltase Deficiency (Glycogenosis type 2; Pompe disease), Debrancherdeficiency (Glycogenosis type 3), Phosphorylase deficiency (McArdle's;GSD 5), X-linked syndrome (GSD9D), Autosomal recessive syndrome (GSD9B),Tarui's disease (Glycogen storage disease VII; GSD 7), PhosphoglycerateMutase deficiency (Glycogen storage disease X; GSDX; GSD 10), Lactatedehydrogenase A deficiency (GSD 11), Branching enzyme deficiency (GSD4), Aldolase A (muscle) deficiency, β-Enolase deficiency,Triosephosphate isomerase (TIM) deficiency, Lafora's disease(Progressive myoclonic epilepsy 2), Glycogen storage disease (Muscle,Type 0, Phosphoglucomutase 1 Deficiency (GSD 14)), and GlycogeninDeficiency (GSD 15).

In some embodiments, a compound provided herein is useful in treatingautoimmune disease. For example, several lines of evidence stronglysuggest that PRMT inhibitors may be valuable for the treatment ofautoimmune diseases, e.g., rheumatoid arthritis. PRMTs are known tomodify and regulate several critical immunomodulatory proteins. Forexample, post-translational modifications (e.g., arginine methylation),within T cell receptor signaling cascades allow T lymphocytes toinitiate a rapid and appropriate immune response to pathogens.Co-engagement of the CD28 costimulatory receptor with the T cellreceptor elevates PRMT activity and cellular protein argininemethylation, including methylation of the guanine nucleotide exchangefactor Vav1 (Blanchet et al., J. Exp. Med. 2005 202:371-377). PRMTinhibitors are thus expected to diminish methylation of the guanineexchange factor Vav, resulting in diminished IL-2 production. Inagreement, siRNA directed against PRMT5 was shown to both inhibitNFAT-driven promoter activity and IL-2 secretion (Richard et al.,Biochem J. 2005 388:379-386). In another example, PRMT1 is known tocooperate with PRMT4 to enhance NFkB p65-driven transcription andfacilitate the transcription of p65 target genes like TNFα (Covic etal., Embo. J. 2005 24:85-96). Thus, in some embodiments, PRMT1 and/orPRMT4 inhibitors, e.g., those described herein, are useful in treatingautoimmune disease by decreasing the transcription of p65 target geneslike TNFα. These examples demonstrate an important role for argininemethylation in inflammation. Thus, without being bound by any particularmechanism, the inhibition of PRMTs, e.g., by compounds described herein,is beneficial in the treatment of autoimmune diseases.

In some embodiments, a compound provided herein is useful in treatingneurological disorders, such as amyotrophic lateral sclerosis (ALS). Forexample, a gene involved in ALS, TLS/FUS, often contains mutatedarginines in certain familial forms of this disease (Kwiatkowski et al.,Science 2009 323:1205-8). These mutants are retained in the cytoplasm,which is similar to reports documenting the role arginine methylationplays in nuclear-cytoplasmic shuffling (Shen et al., Genes Dev. 199812:679-91). This implicates PRMT, e.g., PRMT1, function in this disease,as it was demonstrated that TLS/FUS is methylated on at least 20arginine residues (Rappsilber et al., Anal. Chem. 2003 75:3107-14).Thus, in some embodiments, the inhibition of PRMTs, e.g., by compoundsprovided herein, are useful in treating ALS by decreasing the amount ofTLS/FUS arginine methylation.

In thefirst step iodopyrazole carboxaldehydes of general formula XI areallowed to react with mono-Boc protected ethylenediamines XII underreductive amination conditions (e.g. sodium cyanoborohydride andcatalytic acid such as acetic acid) in an appropriate solvent such asmethanol to give intermediates of general formula XIII. In certainembodiments, Sonagashira reaction of intermediates of general formulaXIII with boronic acids or boronic esters of general formula XIV inwhich L_(1′) is an acetylene linker and Q is a boronic acid or boronicester group in the presence of a palladium catalyst (e.g. PdCl₂(dppf))and a base (e.g. potassium carbonate) in an organic solvent (e.g.toluene) at elevated temperature yields intermediates of general formulaXV-a in which L_(1′) is an acetylene linker. Boc deprotection ofintermediates of general formula XV-a gives acetylene compounds offormula VI-a. In certain embodiments, Suzuki reaction of intermediatesof general formula XIII with boronic acids or boronic esters of generalformula XIV in which L_(1′) is a trans-olefin linker and Q is a boronicacid or boronic ester group in the presence of a palladium catalyst(e.g. PdCl₂(dppf)) and a base (e.g. potassium carbonate) in an organicsolvent (e.g. toluene) at elevated temperature yields intermediates ofgeneral formula XV-b in which L_(1′) is an olefin linker. Bocdeprotection of intermediates of general formula XV-b gives olefincompounds of formula VI-b. In certain embodiments, Suzuki reaction ofintermediates of general formula XIII with pinacol boranes of generalformula XIVc in which L_(1′) is bond, R^(W′) is a heterocycloalkenyl orcycloalkenyl group and Q is a pinacol borane group yields intermediatesof general formula XV-c in which L_(1′) is bond and R^(W′) is aheterocycloalkenyl or cycloalkenyl group. In certain embodiments,compounds of formula I wherein L₁ is bond and R^(W) is a heterocyclyl orcarbocyclyl group can be prepared by hydrogenation of intermediates offormula XV-c followed by Boc deprotection. In certain embodiments,compounds of formula I where L₁ is —O— can be synthesized fromintermediates of general formula XIII by Goldberg reaction with alcoholsof formula R^(W)OH followed by Boc deprotection. In certain embodiments,compounds of formula I where L₁ is —N(R^(B))— can be synthesized fromintermediates of general formula XIII by palladium catalyzed Buchwaldcoupling reaction conditions with amines of formula R^(W)N(R^(B))Hfollowed by Boc deprotection. In certain embodiments, compounds offormula I where L₁ is —C(═O)NR^(B)— can be synthesized fromintermediates of general formula XIII under known copper catalyzedcoupling reaction conditions of amides with aryliodides using copperiodide an amine ligand and a base with amides of formulaR^(W)C(═O)NHR^(B) followed by Boc deprotection.

Scheme 1.1 shows an alternative general synthesis route to pyrazolecompounds of Formula (I), that involves reversal in the order of thefirst two steps of the reaction sequence detailed for Scheme 1.0. Thus,in the first step iodopyrazole carboxaldehydes of general formula XI arecoupled with compounds or reagents of general formula XIV (e.g. viaSuzuki reaction with pinacol boranes of general formula XIVc in whichL_(1′) is bond, R^(W′) is a heterocycloalkenyl or cycloalkenyl group andQ is a pinacol borane group) and in a second step the correspondingreductive amination reaction to yield common intermediates of generalformula XV is a carried out.

In certain embodiments, iodopyrazole carboxaldehydes of general formulaXI may be prepared from suitable known pyrazole compound intermediatesby established synthetic chemistry methods. Standard methods includedirect iodination of a pyrazole 3-carboxylate and Sandmeyer reaction ofa 3-amino pyrazole 4-carboxylate. In certain embodiments, iodopyrazolecarboxaldehydes can be derived from iodopyrazole carboxylates byreduction to a hydroxymethyl group followed by oxidation tocarboxaldehyde. In certain embodiments, mono-Boc protectedethylenediamines XII can be synthesized by standard methods known in theliterature for derivatizing or preparing ethylenediamines. For exampleintermediates of formula XII may be prepared by treatment of thecorresponding unprotected diamine precursors with Boc₂O and purifyingthe mixture of mono and dibocylated products. In certain embodiments,pyrazole compounds of general formula II can be prepared fromiodopyrazole carboxaldehydes of general formula XXI as depicted inScheme 2. In certain embodiments where R⁴ is hydrogen compounds ofgeneral formula II are equivalent to compounds of general formula IIIwhich are tautomers. In certain embodiments, R^(4′) is a protectinggroup such as tetrahydropyranyl (THP) which maybe cleaved to hydrogenunder acidic conditions in the final Boc-deprotection step. In certainembodiments, iodopyrazole carboxaldehydes of general formula XXI can beprepared as depicted in Scheme 3.

In certain embodiments, iodopyrazole carboxaldehydes of general formulaXXI can be prepared as depicted in Scheme 4 which also providesiodopyrazole carboxyaldehydes of general formula XXXI. In certainembodiments, alkylation of intermediates of general formula XXX gives amixture of pyrazole nitrogen alkylated isomers which are separated bychromatography to give pure isomers XXI and XXXI. In certainembodiments, pyrazole compounds of general formula III can be preparedfrom iodopyrazole carboxaldehydes of general formula XXXI as depicted inScheme 5.

In certain embodiments, pyrazole compounds of general formula IV can beprepared from iodopyrazole carboxaldehydes of general formula XLI asdepicted in Scheme 6.

In certain embodiments, iodopyrazole carboxaldehydes of general formulaXLI and LI can be prepared as depicted in Scheme 7. In certainembodiments, an R⁴ group of iodopyrazole carboxaldehydes may beintroduced by alkylation of intermediates of formula XLVII. Thisreaction can give a mixture of intermediate compounds of formulas XLIand LI which may be separated by chromatography.

Compounds in 100% DMSO (1 ul) were spotted into apolypropylene 384-well V-bottom plates (Greiner) using a Platemate Plusoutfitted with a 384-channel head (Thermo Scientific). DMSO (1 ul) wasadded to Columns 11, 12, 23, 24, rows A-H for the maximum signal controland 1 ul of SAH, a known product and inhibitor of PRMT1, was added tocolumns 11, 12, 23, 24, rows I-P for the minimum signal control. Acocktail (40 ul) containing the PRMT1 enzyme was added by MultidropCombi (Thermo-Fisher). The compounds were allowed to incubate with PRMT1for 30 min at room temperature, then a cocktail (10 ul) containing SAMand peptide was added to initiate the reaction (final volume=51 ul). Thefinal concentrations of the components were as follows: PRMT1 was 0.5nM, ³H-SAM was 200 nM, non-radiolabeled SAM was 1.5 uM, peptide was 20nM, SAH in the minimum signal control wells was 1 mM, and the DMSOconcentration was 2%. The assays were stopped by the addition ofnon-radiolabeled SAM (10 ul) to a final concentration of 300 uM, whichdilutes the ³H-SAM to a level where its incorporation into the peptidesubstrate is no longer detectable. 50 ul of the reaction in the 384-wellpolypropylene plate was then transferred to a 384-well Flashplate andthe biotinylated peptides were allowed to bind to the streptavidinsurface for at least 1 hour before being washed once with 0.1% Tween20in a Biotek ELx405 plate washer. The plates were then read in aPerkinElmer TopCount plate reader to measure the quantity of ³H-labeledpeptide bound to the Flashplate surface, measured as disintegrations perminute (dpm) or alternatively, referred to as counts per minute (cpm).

Protein Purification. Expressed full-length human Flag- and His-taggedCARM1 protein was purified from cell paste by anti-flag M2 affinitychromatography with resin equilibrated with buffer containing 20 mMTris, 150 mM NaCl, 5% glycerol, pH 7.8. Column was washed with 500 mMNaCl in buffer A and Flag-CARM1-His was eluted with 200 ug/ml FLAGpeptide in buffer A. Pooled fractions were dialyzed in 20 mM Tris, 150mM NaCl, 5% glycerol and 1 mM DTT, pH 7.8. The purity of recoveredprotein was 94.

General Procedure for CARM1 Enzyme Assays on Peptide Substrates. Theassays were all performed in a buffer consisting of 20 mM Bicine(pH=7.6), 1 mM TCEP, 0.005% BSG, and 0.002% Tween 20, prepared on theday of use. Compounds in 100% DMSO (1 ul) were spotted into apolypropylene 384-well V-bottom plates (Greiner) using a Platemate Plusoutfitted with a 384-channel head (Thermo Scientific). DMSO (1 ul) wasadded to Columns 11, 12, 23, 24, rows A-H for the maximum signal controland 1 ul of SAH, a known product and inhibitor of CARM1, was added tocolumns 11, 12, 23, 24, rows I-P for the minimum signal control. Acocktail (40 ul) containing the CARM1 enzyme was added by MultidropCombi (Thermo-Fisher). The compounds were allowed to incubate with CARM1for 30 min at room temperature, then a cocktail (10 ul) containing³H-SAM and peptide was added to initiate the reaction (final volume=51ul). The final concentrations of the components were as follows: CARM1was 0.25 nM, ³H-SAM was 30 nM, peptide was 250 nM, SAH in the minimumsignal control wells was 1 mM, and the DMSO concentration was 2%. Theassays were stopped by the addition of non-radiolabeled SAM (10 ul) to afinal concentration of 300 uM, which dilutes the ³H-SAM to a level whereits incorporation into the peptide substrate is no longer detectable. 50ul of the reaction in the 384-well polypropylene plate was thentransferred to a 384-well Flashplate and the biotinylated peptides wereallowed to bind to the streptavidin surface for at least 1 hour beforebeing washed once with 0.1% Tween20 in a Biotek ELx405 plate washer. Theplates were then read in a PerkinElmer TopCount plate reader to measurethe quantity of ³H-labeled peptide bound to the Flashplate surface,measured as disintegrations per minute (dpm) or alternatively, referredto as counts per minute (cpm).

% Inhibition Calculation

${\% \mspace{14mu} {inh}} = {100 - {\left( \frac{{dpm_{cmpd}} - {dpm_{m\; i\; n}}}{{dpm_{m\; {ax}}} - {dpm_{m\; i\; n}}} \right) \times 100}}$

Where dpm=disintegrations per minute, cmpd=signal in assay well, and minand max are the respective minimum and maximum signal controls.

Four-Parameter IC50 Fit

$Y = {{Bottom} + \frac{\left( {{Top} - {Bottom}} \right)}{\left( {1 + \left( \frac{X}{{IC}_{50}} \right)^{{Hill}\mspace{14mu} {Coefficient}}} \right.}}$

Where top and bottom are the normally allowed to float, but may be fixedat 100 or 0 respectively in a 3-parameter fit. The Hill Coefficientnormally allowed to float but may also be fixed at 1 in a 3-parameterfit. Y is the % inhibition and X is the compound concentration.

RKO Methylation Assay

RKO adherent cells were purchased from ATCC (American Type CultureCollection), Manassas, Va., USA. DMEM/Glutamax medium,penicillin-streptomycin, heat inactivated fetal bovine serum, 0.05%trypsin and D-PBS were purchased from Life Technologies, Grand Island,N.Y., USA. Odyssey blocking buffer, 800CW goat anti-rabbit IgG (H+L)antibody, and Licor Odyssey infrared scanner were purchased from LicorBiosciences, Lincoln, Nebr., USA. Mono-methyl arginine antibody waspurchased from Cell Signaling Technology, Danvers, Mass., USA. Methanolwas purchased from VWR, Franklin, Mass., USA. 10% Tween 20 was purchasedfrom KPL, Inc., Gaithersburg, Md., USA. DRAQ5 was purchased fromBiostatus Limited, Leicestershire, UK.

RKO adherent cells were maintained in growth medium (DMEM/Glutamaxmedium supplemented with 10% v/v heat inactivated fetal bovine serum and100 units/mL penicillin-streptomycin) and cultured at 37° C. under 5%CO₂.

Cell treatment, In Cell Western (ICW) for detection of mono-methylarginine and DNA content. RKO cells were seeded in assay medium at aconcentration of 20,000 cells per mL to a poly-D-lysine coated 384 wellculture plate (BD Biosciences 356697) with 50 μL per well. Compound (100nL) from a 96-well source plate was added directly to 384 well cellplate. Plates were incubated at 37° C., 5% CO₂ for 72 hours. After threedays of incubation, plates were brought to room temperature outside ofthe incubator for ten minutes and blotted on paper towels to remove cellmedia. 50 μL of ice cold 100% methanol was added directly to each welland incubated for 30 min at room temperature. After 30 min, plates weretransferred to a Biotek EL406 plate washer and washed 2 times with 100μL per well of wash buffer (1×PBS). Next 60 μL per well of Odysseyblocking buffer (Odyssey Buffer with 0.1% Tween 20 (v/v)) were added toeach plate and incubated 1 hour at room temperature. Blocking buffer wasremoved and 20 μL per well of primary antibody was added (mono-methylarginine diluted 1:200 in Odyssey buffer with 0.1% Tween 20 (v/v)) andplates were incubated overnight (16 hours) at 4° C. Plates were washed 5times with 100 μL per well of wash buffer. Next 20 μL per well ofsecondary antibody was added (1:200 800CW goat anti-rabbit IgG (H+L)antibody, 1:1000 DRAQ5 (Biostatus limited) in Odyssey buffer with 0.1%Tween 20 (v/v)) and incubated for 1 hour at room temperature. The plateswere washed 5 times with 100 μL per well wash buffer then 2 times with100 μL per well of water. Plates were allowed to dry at room temperaturethen imaged on the Licor Odyssey machine which measures integratedintensity at 700 nm and 800 nm wavelengths. Both 700 and 800 channelswere scanned.

Calculations: First, the ratio for each well was determined by:

$\left( \frac{{monomethyl}\mspace{14mu} {Arginine}\mspace{14mu} 800\mspace{14mu} {nm}\mspace{14mu} {value}}{{DRAQ}\; 5\mspace{14mu} 700\mspace{14mu} {nm}\mspace{14mu} {value}} \right)$

Each plate included fourteen control wells of DMSO only treatment(minimum activation) as well as fourteen control wells for maximumactivation treated with 20 μM of a reference compound. The average ofthe ratio values for each control type was calculated and used todetermine the percent activation for each test well in the plate.Reference compound was serially diluted three-fold in DMSO for a totalof nine test concentrations, beginning at 20 μM. Percent activation wasdetermined and EC₃₀ curves were generated using triplicate wells perconcentration of compound.

${{Percent}\mspace{14mu} {Activation}} = {100 - \left( {\left( \frac{\left( {{Individual}\mspace{14mu} {Test}\mspace{14mu} {Sample}\mspace{14mu} {Ratio}} \right) - \left( {{Minimum}\mspace{14mu} {Activation}\mspace{14mu} {Ratio}} \right)}{\left( {{Maximum}\mspace{14mu} {Activation}\mspace{14mu} {Ratio}} \right) - \left( {{Minimum}\mspace{14mu} {Activation}\mspace{14mu} {Ratio}} \right)} \right)*100} \right)}$
